I have here an Asus Eee pc, model is the 1005peb version. Now for the most part it runs fairly decent and quick, not much issue with it except one major one.

Every time I restart or turn on the netbook my brightness is set to full yet my screen is like almost full on black, like it's turned off. I turn down the brightness a couple times using the Fn + F5/F6 keys and it goes nice and bright etc. When I turn the netbook on I have to turn down my brightness level to see the screen at what (I think) is full brightness and it's then ok. If I turn it off and restart etc I have to do it all over again.

Down is up kinda thing...it's an odd and annoying issue, one that I cannot find an answer for anywhere. So if anyone has a solid way of getting it fixed I would be most appreciative. Thanks!

I'm using Ubuntu 11.04, Desktop Edition, Standard Grub settings and Kernel no changes to any of the hardcore system settings...

I tried Ilari Kajaste's suggestion and it had no effect. Neither better nor worse.

@fossfreedom I'll look deeper into your suggestion but at this time it looks almost the same as the second answer so I doubt it is what I currently seek.

Has your question been solved? I could reassign the bounty here if you want, since I got the bounty even though my solution did not fix your issue.

@zkriesse - did you check your BIOS version and jupiter package as per my answer? Finally enough I had a similar issue with my Toshiba running Lucid. In the end I installed a newer kernel (2.6.37 vs 2.6.32) and this fixed it for me.

What do your settings tell you in /etc/laptop-mode/conf.d/lcd-brightness.conf

The lcd-brightness module allows you to control the brightness of your
LCD screen.

CONTROL_BRIGHTNESS
When this option is enabled, laptop mode will adjust your LCD
screen’s brightness settings, if possible. You must configure
the following settings for this to work.
BATT_BRIGHTNESS_COMMAND
LM_AC_BRIGHTNESS_COMMAND
NOLM_AC_BRIGHTNESS_COMMAND
BRIGHTNESS_OUTPUT
The BRIGHTNESS_COMMAND settings specify commands that should
be executed in order to set the brightness of your LCD. The
BRIGHTNESS_OUTPUT setting specifies where the output of the
command will be written. For instance, if your LCD’s
brightness is adjusted by writing a numeric value 3 to a file
called /proc/brightness, you should set the command to "echo
3" and the output file to "/proc/brightness". If your LCD’s
brightness is adjusted using a utility like "toshset", you
should include the entire toshset command line as the
command, and set the output file to "/dev/null".

it'a one abnormal behaviour on asus eeepc notebook with Fn brightness keys on ubuntu 14.04. when you press Fn+F5, or Fn+F6 keys to change brightness, brightness jumps almost twice. it's said about, it's a matter of performing brightness change action first by acpi and after that by Xserver, so the result is, brightness changes faster, in larger steps than you like or expect. for me have worked one slighlty different solution, change line at /etc/default/grub as many authors suggest, but insted of acpi_backlight=vendor use acpi_backlight=off use as well acpi_osi=Linux otherwise brightness change will not works totally.

There's no need to install laptop-mode-tools or other packages...
but this will cause, brightness change information slider doesn't appear as before (Xserver action is not performed), but brightness changes in normal, BIOS supported steps, it seems to me it's 10 steps at asus eeepc. maybe this can be solution on more problems you've posted.
